I am facing a strange issue on LPC1227. When it runs without debugger, everything seems to be OK. When debugger is on, sometimes intterrupts just stop firing. Or they are firing, but the ISR functions are not called. I have systick and UART interrupt. I checked the global interrupt enable flag and local flags of systick and UART and they seem to be OK. Under what circumstances can this happen? What am I missign here?

Thanks in advance.
